A gel mattress is a type of mattress that is infused with a special layer of gel in between layers of foam or on the mattress's top. The gel helps the sleeper maintain an optimal body temperature while distributing body weight and providing relief to pressure points.
Gel mattresses are similar to memory foam mattresses and sometimes incorporated into the design of the memory foam mattress. These mattresses relieve lower back pain by helping the sleeper attain optimal spinal alignment. It also eliminates pressure for side sleepers. Gel mattress pads and pillows are also available for people who don't want to invest in a mattress.
